problem: NTB ASUS A6va - změna CPU = změna pass do BIOSU

[Luckyboy]

Ahoj!Postestilo se mi sehnat silnejsi CPU, tak jsem jej nainstaloval a celej stastnej, ze jsem neporusil ochrannou znamku co je na chladici pustil jsem NTB a ejhle BIOS po me chce heslo. Kdyz jsem googlil tak jsem narazil na to, ze u NTB je to jinak nez u klasickych desek, takze si netroufam pouzivat klasicke metody ruseni hesel(SW i HW). Uprimne receno ani nevim kde bych napriklad hledal nejaky jumper nebo baterku abych vymazal nastaveni v cmos. Bohuzel si myslim ze pouhe vymazani CMOS asi nebude k nicemu. Predem diky vsem za rady!

NTB = ASUS A6va Q044

UTFG!
Pro urcite NB jsou tzv. backdoorove hesla (univerzalni), pro TOSHIBA NB je mozno si udelat "bootovaci disketu", ktera zrusi heslo. A pokud to heslo po tobe chce jenom pro vstupu do biosu a dostanes se do widlí, existujou programy, co ti to heslo rozlousknou.

UTFG!!!

No googlil jsem...prave proto se tu ptam. Vygooglil jsem, ze to heslo neni ulozeny v cmos-a napr. u toshiby se to rusi nejakym klicem do lpt. Je to ulozeny nekde v eeprom jak je ulozenej bios - je to logicke. Prave proto se tu ptam nez se do neceho pustim. Napr. cituji z read me u cmospwd
"On laptops, the password is usually stored in an eeprom on the motherboard,
you need an eeprom programmer (electronic device) to retrieve it.
" .
Ale i tak dekuji za vas prispevek. Sice mi moc nepomohl a zkratka utfg me trosku pobourila, ale pokud jsem neco nevygoogli pred par dny neznamena , ze vy jste neco dnes nemohl vygooglit(doufam, ze je vam jasny princip google a celkove fakt, ze internet se meni velmi dynamicky).
Take nepopiram, ze jsem nemohl prehlednou nejaky odkaz. Moc bych vas tedy prosil, jestli by jste mi nemohl poslat odkaz pokud jste na neco narazil.

Ahoj,
smal jsem se, protoze jsem si vcera zahesloval NB a to pekelnym heslem, ktere nikdo neprolomi. Ma to jeden hacek, dokonce ani ja jej neprolomim Mam NB znacky TOSHIBA a na nej se daji aplikovat ruzne metody resetovani, ci preskoceni hesla. Nize je jich par popsanych. Strucne: 1) Backdoor heslo,
2)vytazeni baterie (te malinke pro udrzeni systemoveho casu) + spojeni-zkratovani dvou kontaktu v niz je baterie zasazena (po dobu alespon 1 minuty)
3) (TOSHIBA) vytvoreni crackovaci diskety

These backdoor passwords have been provided to you free of charge. If you have attempted to use these backdoor passwords on a system (even just as a test), we would appreciate knowing whether these backdoors have worked for you. Please email us at pwcrack@pwcrack.com with the BIOS ID number, whether or not the backdoor worked, and which backdoor worked. This information will help us assist others in the future. The AMI or Award BIOS ID appears at the bottom of the screen after power on.


In BIOS’ with a release date of December 19, 1996 or later, Award required OEM customers to configure their own security default BIOS passwords using the Award MODBIN.EXE utility, version 4.50.60. If you are aware of any other backdoor BIOS passwords please let us know at pwcrack@pwcrack.com.


If you are unable to recover the password with a BIOS password cracker or a backdoor there may still be options available. However, we recommend that the additional work only be attempted by a qualified technician.


RECOVERY IF YOU CANNOT BOOT THE SYSTEM


If you cannot boot the system without the BIOS password, then using a BIOS password cracker is not going to work (since you cannot run the program.) You should first attempt to gain access to the system by using the backdoor passwords listed above. For many desktop type PC’s, BIOS passwords can be reset by removing the CMOS battery for a number of hours. However, care should be taken when attempting recovery in this way since this method may also clear any BIOS customizations and render PC components inoperable.


LAPTOP AND NOTEBOOK RECOVERY


Most laptop manufacturers have provided additional safeguards for their computers. We are not aware of any simple BIOS recovery program that works on laptops, nor are we aware of any simple backdoor passwords for these machines. BIOS passwords in most laptops are stored in a special chip on the motherboard and the only way to bypass this password is to replace this laptop security chip. Laptop BIOS passwords cannot be bypassed or reset by removing or shorting the CMOS battery. Further, doing this may cause other system errors and complicate the recovery or your system.


We offer a full-range of replacement laptop security chips. These chips will allow you to bypass the laptop BIOS password. Note that these chips will require soldering on the system board (a hot air soldering kit is also available.) Since these chips store the laptop BIOS passwords, replacing the laptop security chip will remove the BIOS password. However, if a hard disk lock password has been set, it will remain. Passwords can be recovered from the original chip removed from the system board using our Password Recovery Service (PRS) for an additional fee. Since the BIOS password and hard disk lock passwords are usually the same, recovering the BIOS password from the old chip may allow you to access the hard disk. However, this is not guaranteed, since these passwords can be set independently. All replacement chips include detailed instructions. Password Crackers, Inc. cannot take any responsibility for damage to system boards, computers or data. More information about our security chips and our chip password recovery service are available on our security chips page.


One exception to the above chip information is the Toshiba Security Access Key. The Toshiba Key allows for the immediate bypass of the BIOS password from most Toshiba models without soldering. More information on the Toshiba Key is available on our Toshiba security chips page.


HARD DISK LOCKS


Some laptops provide a utility to lock a hard disk with a password. These passwords are not the same as BIOS passwords. Moving a locked hard disk to another machine will not unlock it, since the hard disk password is stored in the hard disk firmware and moves with the hard disk. Also, adding a new (unlocked) hard disk to a locked machine may cause the new hard disk to become locked. Also, note that hard disk lock passwords cannot be removed by reformatting the disk, fdisk or any other software procedure (since the disk will not allow and reads or writes to the disk, it cannot be reformatted.) Usually, the BIOS password and hard disk lock passwords are set the same by a user and we can recover the BIOS password directly from the laptop security chip (after it is removed from the system board.) However, it is possible that the BIOS password and hard disk lock passwords may be set different. In this case the BIOS password will not unlock the hard disk. You can test to determine if your hard disk is locked by attempting to access it in another laptop. Password Crackers, Inc. offers a service that can unlock most models of laptop hard disks. Detail are available on our hard disk page.

Ve Tvem pripade se obavam, ze zbyva pouze modlit se v backdoor, nebo snadno pristupnou baterku GL

[Luckyboy]

Ahoj!
Diky za reakci...samoze backdoorovy hesla jsem vyzkousel jeste nez jsem sem psal-a prozmenu nefunkcni no a na tu stranku z ktere jsi zkopiroval ten text jsem taky narazil...a i tam pisou o problematice laptopovych biosu...konkretne ze se musi prehrat v ctece(zapisovacce) na eeprom. No a taky jak uz jsem psal existuji konkretne pro toshibu moznost odstraneni hesla pomoc klice-je to do lpt a neni to ani tezky na zbastleni a na schematko jsem nekde narazil takze to asi nebude problem dohledat.
Jinak me napada jak si vyrobce muze dovolit mi znemoznovat pristup do biosu. Ikdyz jsem tim porusil zaruku, tak to nemeni nic na tom ze ja jako vlastnik bych mel mit tu moznost si stim delat co chci. Odtoho jsou tam ti servisaci co maji prijit na to ze jsem zmenil konfiguraci a ne mi sproste znemoznit pristup do biosu. Teda ne ze by tam bylo neco vyznamneho...moznosti k nastaveni je tam velmi poskromnu. Ale napr kalibrace baterky je docela dulezita.
